    marketDataUpdate.Price of second instrument

    I have written a code that display the last price traded in the chart and it works ok.

    But what I want is to display the last price of another instrument without including in the data series of the chart.When I call for the second data serie in the indicator there is an error in marketDataUpdate.Price[1]...



    //else if (State == State.Configure)
    //{
    // AddDataSeries("ES 12-20", Data.BarsPeriodType.Tick, 1, Data.MarketDataType.Last);
    //}
    }

    protected override void OnBarUpdate(){}

    protected override void OnMarketData(Data.MarketDataEventArgs marketDataUpdate)
    {

    if (BarsInProgress != 0)
    return;

    if (CurrentBars[0] < 1
    || CurrentBars[1] < 0)
    return;


    if (marketDataUpdate.MarketDataType == MarketDataType.Last)

    Draw.TextFixed(this, "", "" + marketDataUpdate.Price[1],TextPosition.TopRight, Brushes.White, new Gui.Tools.SimpleFont("Arial", 12), Brushes.Transparent, Brushes.Transparent, 100);
    }

    Would it be possible in another way?

    Thanks a lot

    Hello Impessa,

    Thanks for your question.

    You can use BarsInProgress checks to differentiate the added data series from from the primary data series. The Data Series must be added with AddDataSeries in order to receive realtime OnMarketData updates for a secondary instrument.

    Code:
    protected override void OnStateChange()
    {
        if (State == State.SetDefaults)
        {
            Name = "MyCustomIndicator6";
            Calculate = Calculate.OnBarClose;
        }
        else if (State == State.Configure)
        {
            AddDataSeries("ES 12-20", Data.BarsPeriodType.Minute, 1, Data.MarketDataType.Last);
        }
    }
    
    protected override void OnMarketData(MarketDataEventArgs marketDataUpdate)
    {
        if (BarsInProgress == 0)
        {
            Print("BIP0: " + Instrument.FullName);
        }
        if (BarsInProgress == 1)
        {
        Print("BIP1: " + Instrument.FullName);
        }
    }
